UNITED STATES PATENT OFFICE.

ALLEN ALFORD, OF BIRMINGHAM, ALABAMA, ASSIGNOR OF ONE-FOURTH TO NOBLESMITHSON, OF SAME PLACE.

' CAR-AXLE.

SPECIFICATION forming part of Letters Patent No. 470,651, dated March15, 1892.

Application filed September 19, 1891. Serial No.406,283. (No model) Toall whom it may concern:

Be it knownthat I, ALLEN ALFORD, a citizen of the United States,residing at Birmingham, in the county of Jefferson and State of 5Alabama, have invented certain new and useful Improvements in Axles; andI do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to improvements in car and other axles, by means ofwhich I provide steel or other metallic sleeves for the same that whenworn down to the limit of safety, instead of requiring a new axle, can tbe refitted or renewed and brought to its original size by fitting itwith steelor other metallic sleeves, and when the sleeves get worn outthey can be renewed by placing others on the axle, thereby using the oldaxle indefinitely.

In the drawings'hereunto annexed, Figure 1 is a plan View of a car-axlefitted with steel or other metallic sleeves on the journal or end. Fig.2 is a sectional view'through the line A 13, showing the steel ormetallic sleeves on the end of the axle in section and the manner ofsecuring the same to the axle. Fig. 3 is an enlarged sectional view -ofthe end of the axle and showing the sleeves attached to the same.

Like letters of reference represent like parts in all the drawings.

is awrought or hammered iron axle. D. D is a steel sleeve placed overthe end or journal of the same.

E E is a left-hand sc1-ew-bolt,tapped into the end of the sleeve andaxle, with the head recessed into the end of the sleeve, and whenscrewed to place prevents the sleeve from turning or coming 03 the axle;

F F is the journal to work in the brasses, and G G is the wheel-bearingto place the wheel on.

The steel or metallic sleeves can be used on new axles when first madeor fitted up. The axle C can be turned up in the usual manner, makingthe journal F the thickness of the sleeve D, smaller than the sizeintended to finish, and a right-hand thread chased on the collar betweenjournal F and wheel-bear- 5o ing G. The sleeve D is turned on the insideto fit, and a thread chased on the inner end, and when finished it canbe screwed firmly on the end of the axle O.

To secure the sleeve D on the axle O and prevent its getting loose orunscrewing in any manner, a hole is drilled in the end of the .sleeve Dand the axle O, and recessed into sleeve D for the head of the bolt 'E.The hole is tapped with a left-hand thread and the bolt E securelyscrewed to place. It prevents the sleeve D getting loose or coming offuntil the bolt E is first taken out.

4 The fitting up of'old or worn axles would be performed in the samemanner as the above description for new. The axle O when once fitteddoes not require to be worked on any more. 7 When worn so that it isnecessary to renew it, the sleeves D D are renewed and new ones put onaxle O, which makes it as good as when first used, thereby creating agreat saving in the cost of renewing worn axles.

I am aware that prior to my invention that caraxles have been made withmetallic sleeves, and I do not claim such a combination, broadly; but

, What I do claim as my invention, and desire to secure by LettersPatent, is v In a car-axle, the combination of the axle So withscrew-threads formed on the thick part outside of the wheel-bearing, anda steel or metallic sleeve with an internal thread chased to fit andscrew on the axle at the above-described point, and a left-handscrew-bolt with 8 5 the head recessed in the end of the sleeve, allsubstantially as described and set forth.

In testimony whereof I affix my signature in presence of two witnesses.

ALLEN ALFORD.
